CLEVlS.

srEcIFIoA'rroN forming art of Letters Patent Ne. 682,361, datedseptemter 10, 1901. Application filed October 15,1900. Serial No.83,117. (No model.)

To ail whom it may concern:

Be it known that 1, WILLIAM R. KEITH, a citizen of the United States,residing at Coalcreek, in the county of Anderson and State of Tennessee,(whose post-office address is Coalcreek, Tennessee,) have invented a NewStyle of Olevis, of Which the following is a specification, referencebeing had to the accompanying drawings, forming part thereof.

Figure 1 is a side view of two of the clevises connected together by anordinary link in the center and with the perpendicular pin in each end.Fig. 2 shows a top view of two of the clevises formed into a mine-carcoupling.

The two clevises A and B, Fig. 1, are eX- actly alike.

The most desirable mode of manufacturing the clevis is by casting it inthe foundry of desirable material, or it may be made in the ordinaryblacksmith-shop by taking a piece of iron or steel, say, four inchesbroad, onehalf inch thick, and fifteen inches long; Take a cleaver andround the four corners. Then out out a slot exactly in the center of thepiece of material about seven inches long and one and one-fourth incheswide. Thoroughly heat the piece of material in the center or theneighborhood of J, Fig. 2. Fold the ends together, as shown at H and I,Fig. 2, shrinking the material over a mandrel at K,where the pin is tobe inserted, thoroughly welding the line L. Bore or punch a hole one andone-half inches in diameter at D, Fig. 1, and insert a pin E or G, asdesired, which will make the clevis complete, ready to beattaoh'ed to aderrick, hoist, mine-car coupling, or anything else that may be desired.

The leading or material feature of my in-- vention is the simpleconstruction and the enormous strength and durability it possesses overthe ordinary clevis and the safety to life and property therefrom. Thesolid material across the clevis from M to N, Fig. 1, will not allow itto spread, and the narrow space 0 gives the pin E or G, Fig. 1, a'muchneeded strength, as simplicity, strength, and durability are thecharacteristics of the invention.

The pins E and G and the link F, Fig. 1, are not claimed in thispetition as new, for they have been in general use for a number ofyears.

What I claim as my invention, and desire to secure by Letters Patent, is

A clevis comprising a plate A provided with a slot 0, cut from thecenter thereof, having the corners of the said plate rounded and bentupon itself, thus forming an opening for the headed pin E, the other endof the clevis being provided with an opening through which passes a linkF by means of which it is pivoted to another clevis identical in form tothe one described, as and for the purpose described.
